Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a template surface cleaning device and a construction method thereof. Background Art

[0002] During the construction of buildings and bridges, the template is usually cleaned and the release agent is applied before the template installation process, but the construction template cleaning process is often easily overlooked. Especially in some projects, the bottom template causes secondary pollution, which is difficult to clean and the cleaning effect is not ideal. Especially in some high-altitude operations, the cleaned welding slag, cement mortar pads, steel bar heads and other solid debris are prone to high-altitude throwing and injuring people, which poses serious safety hazards. For example, the secondary cleaning of the bottom template of the high pier and large cantilever cap beam, due to the installation of the steel cage and the welding of the embedded bellows after the installation of the bottom template, welding slag, broken cement mortar pads, steel bar heads, dust and other debris will fall on the bottom template. During the concrete pouring process, these impurities will be mixed into the concrete. On the one hand, this will change the mix ratio of the concrete and affect its strength development. For example, too many impurities may cause weak points inside the concrete, reduce the compressive and tensile strength, and more easily crack and damage when bearing loads. On the other hand, impurities will also affect the appearance quality of the concrete. For example, dust may cause the concrete surface to have a pockmarked surface, seriously affecting the aesthetics of the building. Due to pollution, part of the concrete may be bonded to the formwork during the later demoulding process, making demoulding extremely difficult. If there are large particles of debris, holes may be formed on the concrete surface, reducing the density of the structure. Moreover, if there is residual release agent from the previous concrete pouring on the formwork and it is unevenly distributed, it may cause the newly poured concrete surface to have inconsistent colors and defects such as mottled patterns.

[0003] To solve this problem, the current construction method is to perform a secondary cleaning of the bottom mold before the cap beam side mold is closed after the preliminary process preparation is completed, and to use a blower and a water gun for flushing. This not only wastes a lot of water resources, but also poses a great safety hazard in high-altitude operations, and the dust from flushing can easily cause environmental pollution.
